How much more oil did you need?
Well I was wondering myself, but like an idiot when I drained the oil I only got maybe 3 to 3.5 gallon out. I just checked the oil last time I drove it and it was full. I know it should hold 5.5 gallons, but I couldn't figure out why I didn't fill up the 5 gallon can I was draining it into. I was a little too excited to see if my new filter setup worked, so instead of finding out where the other 2 gallons went to, I filled it back up with new oil, but ended up over filling it. After I ran it for a minute, I started looking at my other truck and spare engine I have thinking my truck has the wrong dipstick or something, but all three were the same. So I came inside and researched on here, but everyone said 22qts like it says on the dash. Then I saw it, "remember there are 2 drain plugs", doh! Needless to say I drained some out of the other drain plug and got it to the proper level, but now my new oil is already black from getting mixed up a little. I know how the oil pan is made it would have two drain plugs, but I didn't even think about it. It didn't help that this was the first time I changed the oil on either of my deuces, but I guess I won't forget now. So through all the over filling and draining, I have no idea, but I would guess maybe an extra gallon.
